Pregnancy Week by Week

From the first weeks of pregnancy, the development of the baby and the health of both the mother and the baby are monitored by a specialist doctor. In this way, early diagnosis of possible medical problems, developmental problems in the baby and problems that may occur at birth can be determined in advance. However, knowing the changes that the expectant mother will experience during pregnancy allows her to make the necessary observations and evaluations for both herself and the baby’s health. Therefore, it is important to provide the expectant mother with guidance information so that the pregnancy can be followed up week by week. You can contact our clinic for   pregnancy follow-up and all other birth practices and make an appointment.

What are the symptoms of pregnancy week by week?
